Kratek opis

The file upload question type can be used to collect file(s) from a user in response to a question. For example, a company with employment opportunities could use this question type to request the candidate to submit/upload his or her updated CV, as well as any other scanned documents in the employment survey.

This question gives the survey designer the ability to restrict the files that can be uploaded by the user in response to the question. For example, the survey administrator can allow only PNG, JPG, and JPEG images which are less than 1 MB in size.

General options

Relevance equation

Opis

If the value of the relevance equation is "1" or "true", the question is "relevant" in the survey context, i.e. it is shown to the survey participant. If not, the question is hidden. Any survey question allows you to specify a relevance equation. This function is the successor of conditions and supports much more complex conditional logic.

Označevanje sintakse

Whenever you save the relevance equation, it is evaluated and syntax-highlighted. Any errors will be color coded so that you can quickly detect and fix them.

Hint: To check if all the relevance equations are used correctly within your survey, read about our show logic file feature.

Veljavne vrednosti

Any equation that makes use of the Expression Manager syntax, without surrounding curly braces.

Hide tip (hide_tip)

Description

Most questions will usually include a tip that says "Please choose one of the following options" or a hint text on how to fill out the question. This attribute allows you to turn off or on this tips/hints.

These tips/hints include validation criteria messages (such as min/max number of answers, min/max/equals sum value). If hide_tip is enabled, these messages will be hidden. However, if the user enters invalid data, the tips will appear. They will be coloured in red, getting changed to green once the validation criteria are met.

Available options

On - the tips/hints are hidden;

Off (default).

Question theme (question_theme)

Description

It allows you to use customized themes for the respective question.

Available options

Your created question themes which are located under the Question themes in the Themes panel.

Note: This feature is under development at the moment.

Always hide this question (hidden)

Opis

If enabled, the question will always be hidden - it will not be displayed to the survey participants. This function can be used in the following scenarios:

If you wish to prefill a question with a URL and you want not to have it displayed on the screen. This overrides any conditions used within the survey because the respective question will not even be embedded on the page.

Note: A common question type that is used with this function is the Equation one.

Available options

Off (default)

CSS class (css_class)

Description

If you want to add special CSS classes to certain questions, you can enter the CSS class name(s) in this box. Make sure you leave an empty space between different class names.

Valid values

Any text string with a space between different CSS class names.

Hint: You can also insert an expression in this box (New in 3.0.0 ). Remember that the output of the expression will not be updated dynamically.

According to the W3C, CSS class names can contain only the characters [a-zA-Z, and 0-9] and ISO 10646 characters U+00A1 and higher, plus the hyphen (-) and the underscore (_). They cannot start with a digit, or a hyphen followed by a digit. LimeSurvey encodes CSS classes, but it does not fix it totally.

Other

Insert page break in printable view (page_break)

This attribute is only active when you actually print a survey from the Printable View. It forces a page break before the question.

Available options

On

Off (default)

Maximum file size allowed (max_filesize)

The maximum size of a file that should be allowed to be uploaded by the user.

Example

If the maximum filesize is set to 1024 KB, any files larger than 1024 KB will be discarded, and the user will be asked to upload a smaller file.

Note: The final value shown to the survey participant is also depending on PHP settings, like post_max_size and upload_max_filesize. Of all three possible values (upload_max_filesize, post_max_size and max_filesize) the lowest one will be shown and used.

Chart type (chart_type)

Description

This attribute allows the survey administrator to choose which type of chart will be displayed to the respondent once he/she finished filling out the survey.

Note: Do not forget to change the question and survey settings in order to have the charts displayed at the end on the survey. For more details, check the wiki section on the display chart question attribute.
